Thanks

That is steep. You can buy the programmer from the US for $199 (+shipping) and DIY....

It costs a bit more than that from the local wholesaler - surprise, surprise. Once you have it though you are unlikely to use it again unless you want to share it with some friends.The upgrade might take 10 mins all going well, however if one of the bits decides it wants to be difficult about accepting the firmware it may take longer. It took a couple of goes for the battery unit on my bike to work properly.I reckon $40 is a fair price

I see your point but that'd be $40 every time you want something changed. So you want full multishift = $40. You ride it a while and decide it's shifting is too slow/fast = $40 more. You change your mind and want only 3 sprocket changes max = another $40. Shimano issue newer firmware = $40 etc etc. Factor in the $80 per visit he was actually quoted....Sharing with friends is definitely a good idea to recoup the outlay and I know someone who has that intention.

but aren't the Etube connectors the same for both 6070 and 9070, therefore you should be able to use the method shown on page 7 (or maybe even 8 ) of the Operating Manual as per Crawf's suggestion? I appreciate that old DA Di2 is entirely different.

The 9070 junction box has a special port for charging and PC connection. It's totally different to the e-tube ports.
